1. When the select signal is a logic high (1), multiplexer 510 transmits the output signal of inverter 504 to the output of generator 404 as output signal VOUT. 当选择信号为逻辑高电平（1）时，乘法器510传输反相器504的输出信号给发生器404的输出作为输出信号VOUT。
2. The basic concept of class D amplifier is to convert the input analog signal into a pulse width modulated signal (PWM signal), then the PWM signal is demodulated to reconstruct the analog signal. 类功率放大器的基本概念就是将欲放大的信号转化为脉宽调制信号，用来驱动开关逆变器。
3. Secondly, the output waveform signal generator can be divided into sine wave signal generator, pulse-wave signal generator, function generator and arbitrary wave generator, and so on. 其次，按输出波形又可分为正弦波、脉冲波、函数发生器和任意波发生器等。
4. Signal laser interferes in fiber coupler, then shaped signal pulse transmits from output port of this pulse shaper. Signal pulse′s waveform is determined by the profile of the nonlinear phase shift. 信号光在耦合器中发生干涉，经过整形的信号光脉冲从脉冲整形器的出射端出射，信号脉冲的波形由非线性附加相移的波形决定。
5. The paper analyses the signal processing with emphasis on Signal to Noise Ratio (SNR) in output of correlator and SNR in signal power spectral density. 并对算法处理中相关器输出中的信噪比（SNR）和功率谱密度中的SNR进行了重点分析。
